T0 allwhom it may concern: 1

Be it known that I, AUGUST C. Knormima citizen of the United States, and a resident of Asbury Park, in the county of Monmouth and State of New Jerse have invented a new and Improved rench, of which the following is a full, clear, and exact description.

This invention relates to improvements in wrenches, an object of the invention being to provide a gear drive socket wrench which can be conveniently used for remov' or replacing nuts which are awkward to reach and operate with wrenches such as ordinarily made.

A further object is to wrench of the character stated, which can be operated to lock the socket against turning movement to permit the full leverage of the wrench to be employed for loosening a nut and then enable the socket to be turned by the gear driven mechanism to complete the removal of the nut.

further object is to provide a wrench of the character stated which can be manufactured and sold at a reasonably low price provide a socket and which will most efficiently erform the th functions for which it is inten ed.

With these and other objects in view the invention consists in certain novel features of construction, and combinations and arrangements of parts, as will be more fully hereinafter descri and pointed out in the claims.

In the accompanying drawin Figure 1 is a sectlonal plan view illustratin my improved wrenc ig. 2'is a fragmentary view in elevation or top plan of Fig.

ig. 3 is a view in section on the staggered line 3-3 of Fig. 1.

Fig. 4 is a view Similar to Fig. 3, showing the parts differently upositioned.

the respective ends of the shaft 6 and the pinion 8 meshes with a beveled pinion 10 onthe inner end ofthe drive shaft 4, the latter having an annular enlargement 11 thereon bearlng against the inner end of the sleeve 3, as clearly shown in Fig. 1.

The angle 2 is provided with a taperin ring 12 in which a short shaft 13 is mounts to turn and is provided with a beveled gear 14 meshing with the beveled inion 9 and driven by the latter. This she 13 is made angular at its outer portion as shown at 15,

d a socket 16 is secured on member 15. This socket 16 is of such size and shape as to engage a nut and can be made interchangeable with other sizes of socket for various sizes of nut, as will be readily understood.

The car 14 is provided with an an lar recess 1% which is of the same cross-sectional s ape as an angular locking block 18, the latter moving in an opening or bearing 19 in the angle 2, and having its end normally spaced from the gear 14 so as to permit the latter a free turning movement. An operating rod 20 projects laterally through e angle 2 and has an operating button 21 on its outer end. This rod 20 is connected by a link 22 with the locking block 18, said link being normally disposed at an angle, as shown In Fig. 3, so that when the rod 20 is drawn outwardly, a longitudinal move will be imparted to the locking block into the recess 17 of pinion or gear 14 and lock the pinion against turning movement.

he operation is as follows: The socket e nut and if greater 16 is ocated over th and is possible through gage the locking block 18 from the pinion 14 and the gearing and power transmission can be operated through the medium of turning the handle 5, as will be readily understood, to quickly turn the nut.

y reason of the construction above described, it can be seen that my improved wrench can be used in awkward places dif- I spirit and scope of the gearing can 7 ficult to reach by the ordinary wrench, and be employed as a socket turning means, or the wrench as a Whole can be utilized as a lever, as occasion may re uire.

arious slight changes might be made in the general form and arrangement of the parts described invention, and hence I do not limit myself to the, precise details set forth, but consider myself at liberty to make such changes and alterations as fairly fall within the the appended claims. eI. claim: V

1. A wrench of the character described, comprising a tubular casing, a shaft supported by the casing at one, end thereof, a nut engaging socket on the shaft, a pinion on the inner end ofosaid shaft having an angular socket therein, an angular locking block movable into and out o engagement comprising without departing from the with said socket and adapted when in engagement with the socket to lock the pinion against turning movement, means for operating the locking block, and means for imparting turning movement to the pinion.

2. A wrench of the character described, a support, a shaft projecting into the su port, a socket on the outer end of the sha t, a pinion on the inner end of the shaft having an angular recess therein, an, angular locking block keyed to the support and movable into and out of the recess a of the pinion, a rod projecting through the connecting the rod whereby support, a link the movement of the rod imparts longitudinal movement to the locking block, and power transmission gearing operativcly engaging said ini'on.
